Clinical Trial Summary

Although High-intensity interval training (HIIT) exercise has emerged in recent years as a powerful time-efficient alternative to moderate-intensity continuous cardiovascular exercise training (MICT) to enhance neuroplasticity, motor, and cognitive functions, its feasibility remains to be determined early after stroke. Our study aims to investigate the feasibility of the HIIT program and its effects on functional abilities, cognitive function, and quality of life in early post-stroke.

Description:

Study design, setting, and ethical considerations:

This study will be a prospective pre-post study that will be conducted at the university hospital of Parakou in Benin. The study protocol will be submitted to the ethics committee of Hasselt University in Belgium and the local biomedical ethics committee of the University of Parakou, Republic of Benin.

Interventions:

The experimental protocol will be preceded by 30 minutes of conventional physiotherapy, including neuromuscular interventions (balance training, postural awareness), musculoskeletal interventions (passive range of motion, stretching, strengthening), and lower-intensity overground walking. The conventional physiotherapy will be followed by 15 min of the rest period, then the experimental protocol consisting of a HIIT program on a recumbent cycle SOLE R92 (HIIT-REC) will be performed three times per week for six successive weeks.21 Training will be performed on non-consecutive days, thereby permitting recovery between sessions. The HIIT procedure will start at 4-min at 30% of the peak workload interspersed with 1-min at 70% of the peak workload at 50 rpm for weeks 1-2 and increased by approximately 5 minutes every two weeks as tolerated to reach 30 minutes from week 5 (4 to 6 repetitions). The training intensity will progress similarly by 5% peak workload two weeks as tolerated to reach 4-min at 40% peak workload interspersed with 1-min 80% peak workload from week-5.22 All sessions will be supervised and performed individually with verbal encouragement.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Feasibility aspects	The feasibility aspects, include recruitment rates (eligible population / consented population x 100), program adherence (attended sessions / total number of sessions x 100), and the safety (percentage of participants who will experience adverse events)	Up to 6 weeks
Primary	The change in the credibility of the treatment and the expectations of the participants	The treatment credibility and participant expectancy for improvement will be assessed with the Credibility and Expectancy Questionnaire (CEQ). The CEQ includes six items assessing a cognitively based credibility factor and an affectively based expectancy factor	Week 1 and Week 6
Secondary	Berg Balance Scale	The Berg Balance Scale will be used to assess balance impairment. It is a 14 item list with each item consisting of a five-point ordinal scale ranging from 0 to 4, with 0 indicating the lowest level of function and 4 the highest level of function. The minimum score is 0 and the maximum score is 56. A score of 56 indicates functional balance and a score < 45 indicates a higher risk of falling.	Week 1 and Week 6
Secondary	5-Repetition Sit-To-Stand test	We will evaluate functional lower extremity strength with the 5-Repetition Sit-To-Stand test. The 5-Repetition Sit-To-Stand test measures the time taken to complete five repetitions of the sit-to-stand maneuver.	Week 1 and Week 6
Secondary	modified Rankin Scale	The modified Rankin Scale (mRS) will be used to evaluate the degree of disability in the daily activities. The mRS is an ordered scale coded from 0 (no symptoms at all) through 5 (severe disability)	Week 1 and Week 6
Secondary	6-min walk test	The 6-min walk test will be used to assess walking endurance. It assesses the distance a participant can walk as fast as possible for 6 min on a 30 m straight line with the option to stop for fatigue at any point.	Week 1 and Week 6
Secondary	10 m walk test	The 10mWT will be used to evaluate walking speed. It assesses the walking speed in meters per second over a short distance	Week 1 and Week 6
Secondary	Mini-Mental Stage Examination	The cognitive functions will be evaluated with the MMSE. It comprises thirty items providing information about orientation, attention, learning, calculation, delayed recall, and construction. The MMSE scores are interpreted as followed: > 25 (normal cognitive status), 18-23 (Mild cognitive impairment), and 0-17 (Severe cognitive impairment)	Week 1 and Week 6
Secondary	The 5-level EQ-5D version	We will use the EQ-5D-5L to assess the health-related quality of life (HRQoL). It comprises five health dimensions such as mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems	Week 1 and Week 6
